Featuring Jon Wesseltoft, Stian Westerhus, Hild Sofie Tafjord, Kevin Drumm and Maja S.K. Ratkje. "For 20 years running, Lasse Marhaug (Jazkamer) has been one of the leading names in noise. All Music At Once is unmistakably Marhaug; with dense blocks of sound slowly building towards cathartic climaxes. And as often characteristic with Marhaug's music; in spite of the sonic violence there is strong sense of composition going on. Marhaug makes Noise Music, not just noise."
